The DEWALT 90572096 is a OEM replacement lock-off obs spring designed for use in DEWALT power tools. This small but critical component functions as part of the lock-off mechanism, providing the return tension needed to keep the lock-off button or lever in its proper position during tool operation. It is a direct factory replacement part intended for repair technicians, authorized service centers, and experienced tradespeople performing tool maintenance.
This spring is used in DEWALT power tool applications where the original lock-off obs spring has worn, fatigued, or broken. It is suited for workshop repairs and field-service scenarios where restoring the lock-off function is required to return a tool to safe, reliable operation.
Designed as an OEM-style replacement spring for DEWALT power tools equipped with a lock-off obs mechanism. Consult the DEWALT parts diagram for your specific tool model to confirm fitment before ordering.
Installation should be performed by a qualified repair technician or authorized service professional. Disconnect and de-energize the tool fully before disassembling any components. Small springs require careful handling during reinstallation to avoid loss or improper seating. Refer to the DEWALT service manual for the specific tool model before beginning any repair procedure.
